Instead, only analyse them on full runs. Since a change in any stub already invalidates the whole result cache, this means we only need to analyse them on full runs and then remember their errors for later.
On pmmp/PocketMine-MP, this reduces the time to re-analyse with a result cache from ~1300ms to ~1000ms on an XPS 17 9710.
This is a rough shot at implementing phpstan/phpstan#5826.
